Stainless frame

Picked up a new customer. I made them a stainless tube frame. All 1.5" square x 16ga tube with a brushed finish. No cleaning required on my end. They were happy with the result & have already ordered another. My phone doesn't take good close-ups so the weld photo is the best I can do.

Looks great! Did you purge? I would love to see more about stainless, and the ways people address purging. I've seen a bit of the work they do at G.H. Grimm the maple equipment manufacturer. These guys recently were forced by buyers of equipment and company,(a new parent company bought them out), to weld instead of solder. There were some who doubted these guys could learn to weld so quickly. Their welds are flawless. They have machined aluminum backers for each joint to purge, and clamp, and suck out heat.
For jobs where this is less practical I want to know how people solve the problem.

All tigged, no purge. It is a cart frame that holds machine parts when they are servicing/cleaning a machine. My customer adds all their pcs./holders, wheels, etc. as well as blending all the exterior weld joints.

Keeping it square can be a pain. I keep measuring as I go to make sure it is staying. If it is getting out of square you can usually adjust which joints you are welding to help pull it back. I had one instance while half way through this that I put a ratchet strap from a top tube to the bottom tube opposite side & pulled it square while welding. When all done sometimes you need to push/pull to make it square.

It can get out of square from the order you weld the joints & sometimes the tubes can be stressed from the mill & heat makes them move differently each time. Best advice I can give is to keep measuring & make adjustments on the go.
